Overview
IMP51 IMP52 1 1/51 1 2 9 DATA COMMUNICATIONS 9-Line SCSI Terminator The 9-channel IMP5219 SCSI terminator is part of IMP's family of highperformance SCSI terminators that deliver true UltraSCSI performance.
The BiCMOS design offers superior performance over first generation linear regulator/resistor based terminators.
IMP's new architecture employs high-speed adaptive elements for each channel, thereby providing the fastest response possible - typically www.
DataSheet4U.
com 35MHz, which is 100 times faster than the older linear regulator terminator approach.
The bandwidth of terminators based on the older regulator/resistor terminator architecture is limited to 500kHz since a large output stabilization capacitor is required.
The IMP architecture eliminates the external output compensation capacitor and the need for transient output capacitors while maintaining pin compatibility with first generation designs.
Reduced component count is inherent with the IMP5219.
The IMP5219 architecture tolerates marginal system designs.
A key improvement offered by the IMP5219 lies in its ability to insure reliable, error-free communications even in systems which do not adhere to recommended SCSI hardware design guidelines, such as improper cable lengths and impedance.
Frequently, this situation is not controlled by the peripheral or host designer.
For portable and configurable peripherals, the IMP5219 can be placed in a sleep mode with an active LOW disable signal.
Quiescent current is typically 375µA and output are in a high impedance state when disabled.
Key Features Ultra-Fast response for Fast-20 SCSI applications Hot swap compatible 35MHz channel bandwidth 3.
5V operation Less than 3pF output capacitance Sleep-mode current less than 375µA Thermally self limiting No external compensation capacitors Implements 8-bit or 16-bit (wide) applications Compatible with active negation drivers (60ma/channel) x Compatible with passive and active terminations x Approved for use with SCSI 1...
